Chicago 10: Speak Your Peace (2007) is a partly-animated film written and directed by Brett Morgen that tells the story of the Chicago Eight.
The film features Actors voices in an animated reenactment of the trial based on transcripts and rediscovered audio recordings, making the film fall in the animated documentary genre. It also contains archive footage of some of the chicago 8 (David Dellinger, Abbie Hoffman, William Kunstler, Jerry Rubin, Bobby Seale, and Leonard Weinglass) and of the protest and riot itself.

Director Brett Morgen interviewed about why he made chicago 10 as an animated documentary

"I was initially drawn to this subject matter for both political and cinematic reasons, I wanted to make a film that would remind people about the importance of exercising one’s constitutional rights. The events in Chicago happened nearly 40 years ago so my goal from the beginning has been to reintroduce this chapter of recent history to a new generation, for they are the ones who will hopefully benefit the most from this story.

Most historical non-fiction is presented as memoir or as a recollection. I like the idea of allowing the audience to experience events as they unfold. This means eschewing talking head interviews and omniscient narration. I think it is important too, when dealing with subjects like Abbie Hoffman, to reveal them as they were seen at the heights of their fame, to preserve the integrity of their youth.

I also didn’t want to make a film that read like CliffsNotes to an era. With eight defendants representing three political organizations and a political convention with three candidates, all set against one of the most complicated political landscapes in recent history, my biggest fear was overwhelming young audiences with a bunch of names and faces that they had never heard of. At the same time, I didn’t want to trivialize the era by giving passing mention to some weighty issues. I knew that this would be somewhat controversial, but once I decided to free myself from the chains of history, I felt that I could make the movie I wanted to make.

I knew that I wanted the audience to “experience” the courtroom rather than hear about it, so that ruled out talking head “eyewitness” interviews, By animating the trial I would not only avoid all of the clichés of historical non-fiction, but I would also be able to make a statement about the circus-like nature of that courtroom".
